摘要
目前,螺旋板式换热器焊接存在焊缝跟踪困难,焊接所导致的偏差存在的缺陷。本文设计和研发了一套基于主动光视觉技术的螺旋焊缝实时跟踪焊接系统,通过焊接前的焊缝特征点提取,焊接时核相关滤波目标跟踪算法进行焊缝的识别和自动跟踪,实验测试表明该方法能够达到螺旋板式换热器的全自动焊接跟踪精度要求。
At present,the welding of spiral plate heat exchanger has the defect of welding seam tracking difficulty and deviation caused by welding.This paper designed and developed a set of real-time tracking based on active light vision technology of spiral seam welding system,by prior to welding the weld feature point extraction,welding nuclear related filter target tracking algorithm for seam tracking,identification and experimental tests show that the method can meet the automatic welding tracking accuracy requirements of spiral plate heat exchanger.
